For true infinite reserve ammo in Garry’s Mod, the server must let the ammo type’s infinite setting apply: configure that type with maxcarry = -2 and set gmod_maxammo to 0 or a negative value. A large positive gmod_maxammo value—its official Sandbox configuration lists 9999 by default—gives you a large but finite reserve, not unlimited ammo. These settings are controlled through the game or server configuration; the official documentation does not show a universal client-side infinite-ammo console command.
Is there an infinite-ammo command in Garry’s Mod?
The official Garry’s Mod documentation describes configuration and Lua methods for ammo, but it does not establish a universal console command that ordinary players can type to enable infinite ammo. Don’t assume commands from other Source games work in Garry’s Mod.
In Sandbox, the relevant setting is gmod_maxammo. It controls players’ maximum reserve ammo. A positive value overrides an ammo type’s own maximum; a value of 0 or below lets that ammo type’s setting apply. See the Facepunch AmmoData documentation and the official Sandbox configuration.
Choose between a large reserve and infinite reserve
| Outcome | Configuration | What it means |
|---|---|---|
| Large finite reserve | Set gmod_maxammo to a large positive number. The official Sandbox configuration lists 9999 as its default. |
A high reserve limit, not true infinity. |
| Infinite reserve for an ammo type | Set gmod_maxammo to 0 or below, and configure the relevant ammo type with maxcarry = -2. |
The ammo type’s infinite setting can apply because the positive-value override is disabled. |
Facepunch’s AmmoData documentation defines -2 as infinite and notes that gmod_maxammo overrides the ammo type’s value when the convar is above 0. The official Sandbox configuration says values 0 and below use the weapon ammo type’s maximum-ammo setting instead.

How to enable it in Sandbox
You need control over the game or server configuration, including the relevant ammo type’s definition. The exact way to edit or apply configuration depends on how the game is hosted; the official documentation establishes the settings, not a single click-by-click setup for every host.
- Decide which ammo type should be infinite. The setting is per ammo type, so identify the type used by the weapon you want to use.
- Set that type’s
maxcarryto-2. This is the documented value for infinite ammo in the AmmoData reference. - Set
gmod_maxammoto 0 or a negative value. This prevents a positive reserve cap from overriding the ammo type’s setting, as described in the Sandbox configuration. - Test with a weapon that uses that ammo type. If its reserve still behaves as a finite amount, check that the setting was applied to the correct ammo type and that
gmod_maxammois not positive.
If you are playing on someone else’s server
You generally cannot assume you can change a server’s ammo rules as an ordinary client. Ask the operator whether the server supports infinite ammo, or check its rules and addons. Permissions and available controls vary by server; the official documentation does not establish how every host exposes these settings.

Sandbox is Garry’s Mod’s default gamemode, and its spawn menu provides access to items such as weapons, props, and entities. That menu is for spawning content; it is not itself an unlimited-ammo switch. See the Facepunch Spawn Menu documentation.
Reserve ammo is not the same as magazine ammo
gmod_maxammo concerns reserve ammo—the rounds a player carries outside the weapon’s loaded clip. It does not automatically enlarge every weapon’s magazine. Facepunch documents player reserve-ammo functions separately from weapon clip methods, including Weapon:Clip1, Weapon:Clip2, Weapon:SetClip1, and Weapon:SetClip2. See the Player API and Weapon API.

Changing ammo through Lua
For scripted behavior, Facepunch documents Player:SetAmmo and Player:GiveAmmo as Lua methods for setting or granting a player’s ammo. These are APIs to use in code, not universal commands to enter in the console. Individual weapons or third-party addons may also implement clip behavior separately; their behavior is not established by the general Sandbox configuration.
